Symptoms

Consider the following scenario:

  • You install Microsoft WebDAV 7.5 for IIS on a computer that is running Internet Information Services (IIS) 7.0 or IIS 7.5.

  • You enable the WebDAV feature on a website that points to a folder. Additionally, you enable Windows Authentication.

  • A user has Read and Delete NTFS permissions on the folder. The user does not have Write permissions on the folder.

  • You create WebDAV authoring rules to enable group access to the user for the content on the website.

  • The user opens a file from the website by using WebDAV, makes┬áchanges, and then tries to save the file.

In this scenario, the user does not receive an "Access Denied" message. Instead, the file to which the user made changes is deleted.

Cause

The issue occurs because of an error in the Webdav.dll module.
